Funny, until I read this it didn't occur to me that this rule smacks of premature optimization. Odd though that often in optimizing an application after it's written we don't often consider something as high level as switching a tabbed interface to pure HTML/CSS from a JS framework plugin. I would guess this is due to cost, but I've never heard anyone articulate it this way...
